Biology Experiment ( SPA task 5)

Conducting the experiment

Apparatus:

3 large containers

Digital camera

Electronic Scale

Materials:

1 bottle of white vinegar

2 raw hen eggs

1 bottle of vegetable oil

1 bottle of sucrose solution (dilute)

Procedure:

Step 1:

Leave the 2 eggs in an empty container.

Step 2:

Slowly pour in the vinegar,enough to fully submerge the hen eggs.

Step 3:

Cover the container and leave it for 5 minutes.

Step 4:
After 5 minutes, take the cover out and observe the hen eggs in the vinegar. Bubbles should start to form about the egg.

Step 5:

Cover back the hen eggs and leave it overnight to deshell the eggs.

Step 6:
After 1 day, pour the vinegar away. Rinse the eggs with water before gently picking it up. Observe and feel the hen egg again.

Step 7:

Measure the mass of each egg and note it down. This will give you the mass of the hen eggs before putting it into respective solutions.

















Step 8:
Take another container and fill it with oil, just enough to fully submerge one hen egg. Slowly submerge the egg.

Step 9:

Take another container and fill it this time with sucrose solution. Gently submerge another de-shelled egg.

Step 10:

Close the 2 containers and leave the experiment overnight.

Step 11:

The next day, take the eggs out and gently rinse them with water.

Step 12:

Measure the mass again. Take note of any changes.
